KNIFE-BLADE BURNISHER.

SPECIFICATION forming part of Letters Patent No. 381,327, dated April-l7, 1988. l

. Application filed Nl'arch 12, less.

To all whom it ma comem: w Be it known that I, DANIEL T. BROWN, of

Roxbury, in the county of Litchfield'and State of Connecticut, have invented new and useful Improvements in KnifeBlade Burnishers; and

I dohereby declare the following to be a full, clear, and exact description of said invention,

reference being had to the accompan'yingdraw ings, and to the'letters or figures of reference marked thereomivhich form' a part of this specification.

My invention relates to devices for burnishing kniferblades, the object thereof being to burnish the edges of blades which are frequently left unfinishedby the ordinary. burnishing devices-in use; and my invention consists in the construction-and combination of parts hereinafter described, and particularly pointed out'in the claim.- I

In the accompanying drawings, which form a part of this specification, Figurel is a perspective view ofmy burnisher. Fig. 2 isa plan thercof, and Fig.3 is an elevation of the same. I V

A suitable base, A, is'provided, and to this base are secured by any suitable means three segment-shaped plates, B B and O, which are point opposite the space between the platesB- made, preferably, of hardened steel.

The plates B B are arranged parallel to each other, with a space between them somewhat greater than the thickness ofone plate, and with their curved faces b parallelto each other.

The plate 0 is secured to the base A at a B, and with thelower portion of its curved face 0 entering said space slightly, for the purpose hereinafter explained.

The faces I) b and c, besides being curved from the base outward t-othe tops of the plates,

I 0 are made convex or rounded in 'a plane from Serial No. 267,001. (No model.)

ation. 1 t V Thecurved or roundedfaces l b and'c of the plates are made perfectly smooth, and upon placing a knife-blade edge downward in the v-shaped space produced by the arrangement above described and'reciprocating said blade in the direction of its length across the smooth faces of the plates a highly polishedand finished surface will be produced on. each side of said blade near its edge. g

It is to be presumed that the blade has previously undergone a burnishing operation by any ordinary or usual means; but bysuch means a rough or unfinished edge is often pro duced by reason of the impracticability of burnishing perfectly close to the edge of the 7 blade. p

The object of my invention is therefore tocomplete the burnish of a knife-blade byproducing a finish on the edgethereof equal to that on'the sides of the blade; 7

g 110W lly described my invention, what I claim isr v 'i In combination with the. base A, the plates B Band C, the lower part of the plate 0 'ex-" tending into the space between the plates B B, l

the faces of said plates being longitudinally curved and transversely rounded, as shown, andflsaid faces being also made smooth, asand ,for the purpose set forth.
